2020-2021学年高中英语云南同步教案：Unit 3 Computer阅读(人教新课标必修2)
2022-2021学年高中英语云南同步教案：Unit 3 Computer阅读（人教新课标必修2）高中英语必修二Unit 3 Computers阅读课的教学设计一、教学设计思路本课设计以WHO AM I?为课堂教学材料，以同学现实生活为动身点和归宿点，以我国《标准》指导教学目标制定，以“5C”外语学习思想指导教学环节设计，旨在进展同学的语言实际运用力气。
本设计以同学中心，运用了图示理论，接受了pair work, group work, class work 等活动形式，串联成环，前后环环相扣，挂念同学理解课文，用自己的英语重新诠释课文，并初步具备学问迁移力气。
二、学习任务分析本单元的中心话题是“计算机”，内容涉及计算机的进展历史、计算机的应用等，其中还谈到包括计算机在内的几种信息技术的载体、智能计算机的制造等等。
不过，整个单元多以计算机为第一人称进行自白，这种拟人的手法使得文章谈起来妙趣横生，抽象的专业学问介绍起来也浅显易懂。
本主旨语篇WHO AM I ?以计算机的口吻自述其进展演化的历史以及计算机在当今世界各个领域的运用。
表达了计算机的进展变化之快以及在生活中用途之广。
三、学习者分析计算机这一话题虽然好玩，但本单元所选语言材料属于科普类说明文，内容较为抽样，文章中也不乏一些专业术语，对于高一同学来说有确定的难度。
目前，同学上课以interpersonal的沟通为主，而interpretative和presentational形式比重不够。
由于文化教学不够重视，同学的跨文化意识不高。
此外，同学跨学科学习的意识不够，语言和信息的双向促进关系的生疏不够。
对于比较策略主要运用在英汉汉英互译的语言层面，未进入文化比较和思维比较。
同学的课外语言活动环境不够丰富和重视程度不够，通常以词汇、语法和写作练习为主，缺乏真实的语言运用。
四、教学目标(1) Language Skills：1. Use “decision making” expressions like “I believe... in my opinion, etc” correctly.（activity 1）2. Develop their predicting and reorganizing skills.（activity 2,3,4,6）3. Write an 100-word passage on “My Robot Friend----Alice”（Task）(2) Language Knowledge：1. Reorganize and share their backgroud information of computers.(activity 1)2. Find and retell the grammar structure of the Present Perfect Passive Voice. (activ ity 5)(3) Emotions and Attitudes1. 通过争辩，能归纳和陈述网络给学校带来的影响；2. 通过辩论，能对外来网络布满奇异，激发自己的制造力的同时形成健康的网络使用态度和习惯。
